LIGHTING  DEPARTMENT 

CITY  OF  TACOMA 


REPORT  OF 

FREDERICK  G.  SIMPSON 

Consulting  Eledtrical  Engineer 


GENERAL 

The  organization  of  the  Lighting  Department  of  the  City  of 
Tacoma  may  be  considered  as  consisting  of  two  separate  and  distinct 
divisions,  the  Accounting  Division  and  the  Engineering  Division.  The 
administration  of  the  former  is  divided  between  the  Commissioner 
of  Public  Works,  the  Comptroller  and  the  Treasurer. 

The  management  of  the  latter  remains  entirely  with  the  Commis- 
sioner of  Public  Works,  who  appoints,  and  acts  through,  the  City 
Electrician. 

Subordinate  to  this  latter  official  are  the  following  sub-departments : 
SUB-STATION. 

METER  DEPARTMENT. 

LINE  CONSTRUCTION  DEPARTMENT. 

ARC  AND  NERNST  LAMP  DEPARTMENT. 

In  addition  to  the  above,  there  has  recently  been  created  a system 
of  maps  and  records  which  is  subordinate,  in  part,  to  the  Accounting 
Division,  and  in  part  to  the  Engineering  Division. 

Electrical  current  is  supplied  by  the  Seattle-Tacoma  Power  Com- 
pany, a corporation  which  operates  a hydro-electric  plant  at  Snoqualmie 
Falls,  distributing  power  from  that  point  to  the  cities  of  Tacoma, 
Seattle  and  Everett,  as  well  as  to  a number  of  towns  and  villages. 

Under  the  terms  of  a contract  entered  into  under  date  of  November 
8,  1907,  between  the  City  of  Tacoma  and  the  Seattle-Tacoma  Power 
Company,  the  latter  agrees  to  furnish  at  the  bus-bars  of  the  city’s 
switchboard  an  amount  of  electrical  current,  not  to  exceed  a maximum 
of  5,000  horsepower,  for  a period  of  five  years,  the  city  agreeing  to 
pay  therefor  at  a rate  of  l*4c  per  kilowatt  hour,  as  indicated  by 
watt-hour  meters  placed  on  the  city’s  feeder  panels.  Such  meters  to 
be  owned  by  the  city. 

For  further  information  in  regard  to  the  provisions  of  this  con- 
vJ  tract,  reference  is  made  to  the  original  thereof,  which  is  filed  in  the 
office  of  the  Commissioner  of  Public  Works.

CITY  OF  TACOMA  LIGHTING  DEPARTMENT. 


ACCOUNTING  DIVISION 

All  detail  records  of  the  department  are  kept  in  the  office  of  the 
Chief  Clerk  of  the  Lighting  Department,  an  official  appointed  by,  and 
acting  under,  the  authority  of  the  Commissioner  of  Public  Works. 

The  principal  records  of  this  office  are  the  meter  registers.  These 
are  books  exhibiting  a record  of  current  consumed  by  each  customer, 
and  are  the  nearest  approach  to  a customer’s  or  individual  ledger 
kept  by  the  department.  They  are  posted  from  the  meter  reader’s 
reports,  extensions  being  made  for  the  net  amount  of  current  con- 
sumed between  meter  readings  at  the  proper  rate  per  kilowatt  hour. 

The  arrangement  of  these  books  is  such  that  it  is  practically 
impossible  to  maintain  the  accounts  in  the  order  of  the  meter 
reader’s  routes,  a circumstance  which  very  much  increases  the  diffi- 
culty and  labor  of  their  keeping.  This  trouble  would  be  entirely 
obviated  by  the  substitution  of  either  loose  leaf  binders,  or  a card 
cabinet,  for  the  present  bound  volumes. 

Bills,  or,  more  properly,  receipts,  are  made  from  data  contained 
in  the  meter  registers,  the  total  number  of  receipts  for  all  electricity 
consumers  in  one  of  the  city  districts  being  transmitted  by  the  Chief 
Clerk  to  the  Treasurer;  at  the  same  time  the  meter  registers,  from 
which  the  receipts  are  made,  are  temporarily  surrendered  by  the 
Chief  Clerk  to  the  Comptroller,  who,  from  the  footings  thereof,  enters 
a charge,  covering  the  entire  amount,  against  the  Treasurer. 

The  above  transaction  creates  a cash  liability  upon  the  part  of  the 
Treasurer  which  is  entirely  artificial,  and,  owing  to  the  lack  of  any 
record  which  would  permit  of  credit  entries  in  the  individual  accounts, 
leaves  that  officer  without  adequate  means  of  protecting  himself 
against  loss. 

The  installation  of  an  individual  ledger  and  the  placing  into  effect 
of  a system  whereby  a charge  could  only  be  made  against  the 
Treasurer  for  cash  paid  into  his  office,  would  certainly  permit  of  a 
more  accurate  understanding  of  conditions  from  an  examination  of 
the  books,  and  would  also  materially  reduce  the  Treasurer’s  hazard 
of  financial  loss,  which  is  now  very  considerable. 

The  general  records  of  the  department  are  in  the  custody  of  the 
Comptroller,  in  whose  office  they  constitute  a part  of  the  general 
records  of  the  city.  Any  consideration  of  the  methods  of  accounting 
applied  to  Lighting  Department  records,  in  this  office,  as  separate 
from  the  other  city  books,  would  be  improper  and  therefore  foreign 
to  this  investigation.  However,  the  fact  that  no  account  has  been 
taken  of  depreciation  (other  than  the  cost  of  repairs  actually  made), 
due  to  age  and  other  causes,  in  the  value  of  the  department’s  property, 
is  evidence  of  the  necessity  of  reducing  certain  property  accounts  at 
the  expense  of  apparent  earnings. 

For  this  reason  it  is  recommended  that  the  property  of  the  depart- 
ment be  inventoried  and  its  value  ascertained  by  a duly  qualified 
board  of  appraisers.  The  results  of  this  appraisal  to  be  used  as  a 
basis  of  entry  in  the  correction  of  the  general  accounts. 

A system  of  maps  and  records  has  recently  been  inaugurated, 
which,  although  far  from  complete  at  present,  is  excellent  in  prin- 
ciple. While,  to  a certain  extent,  the  work  of  this  department 
belongs  to  the  Accounting  Division,  its  greater  importance  is  in  con- 
nection with  the  Engineering  Division,  and  it  will  be  mentioned 
further  under  that  heading.

ENGINEERING  DIVISION 


City  Electrician. 

Under  the  present  organization  the  office  of  the  City  Electrician 
is  little  more  than  that  of  a general  foreman.  His  remuneration 
and  the  duties  required  of  him  are  upon  a par  with  tfyose  connected 
with  such  a position  in  the  order  of  most  public  service  corporations 
engaged  in  the  sale  of  electric  current.  There  should  be  created  the 
office  of  Superintendent  (or  Manager)  of  the  Lighting  Department, 
which  should  at  all  times  be  filled  by  a man  experienced  in  the 
management  of  properties  of  similar  nature  and  magnitude.  He 
should  also  be  possessed  of  a thorough  technical  understanding  of 
the  matter  and  forces  under  his  supervision.  It  is,  of  course,  super- 
fluous to  say  that  such  an  office  should  in  no  sense  be  of  a political 
nature. 

Sub-Station. 

All  control  apparatus  is  located  in  the  sub-station  building  of  the 
Seattle-Tacoma  Power  Company,  at  Hood  and  Nineteenth  streets,  and 
consists  of  sixteen  marble  panels  carrying  instruments  for  the  regu- 
lation of  alternating  current  commercial  feeder  circuits,  two  wooden 
panels  temporarily  arranged  for  the  same  purpose,  and  thirteen  marble 
panels  for  the  control  of  the  same  number  of  series  street  lighting 
circuits. 

In  addition  to  the  above  there  is  one  direct  current,  600  volt 
power  circuit,  and  one  series  street  lighting  circuit,  the  instruments 
for  the  control  of  which  are  temporarily  mounted  on  wooden  panels. 

The  present  system  of  distribution  consists  of  eleven  single  phase 
and  one  four-wire  two-phase  commercial  circuits,  carrying  alternating 
current  at  a frequency  of  7,200  alternations  per  minute,  and  at  a 
nominal  pressure  of  2,300  volts;  one  600  volt  direct  current  commer- 
cial power  circuit,  and  fourteen  alternating  current  6.6  ampere  series 
street  lighting  circuits. 

Two  phase  alternating  current  at  2,300  volts  potential  is  delivered 
by  the  Seattle-Tacoma  Power  Company  to  bus-bars  placed  in  the  rear 
of  a switchboard  consisting  of  ten  marble  feeder  panels.  These  ten 
panels  constitute  the  original  commercial  switchboard  and  are  at 
present  occupied  from  left  to  right  as  follows:

CITY  OF  TACOMA  LIGHTING  DEPARTMENT. 


The  two  latter  circuits  are  not  as  yet  removed  from  their  old 
panels,  and  can  be  controlled  from  either  the  old  or  new  board. 

A wooden  panel,  No.  11,  carries  the  “Commercial  Street”  circuit, 
while  a two  phase  circuit  designated  “Tide  Flats  Circuit”  has  its 
instruments  temporarily  mounted  on  a wooden  frame. 

All  of  the  above  circuits  receive  current  from  the  bus-bars  above 
mentioned,  to  which  power  is  delivered  by  the  Seattle-Tacoma  Power 
Company,  through  a polyphase  graphic  recording  watt-meter.  This 
instrument  produces  a record  showing  the  load  upon  the  above  men- 
tioned bus-bars  at  all  hours. 

During  the  period  of  this  investigation  all  power  received  for  the 
city’s  street  lighting  system  was  taken  from  these  bus-bars  and  was 
therefore  recorded  as  a part  of  the  load  indicated  by  the  graphic 
watt-meter.  It  is,  however,  the  practice  at  times  to  service  the  street 
lighting  circuits  direct  from  the  bus-bars  of  the  Seattle-Tacoma  Power 
Company,  and,  at  such  times,  the  load  produced  by  them  is  recorded 
on  the  chart  of  a Bristol  recording  watt-meter. 

The  600  volt  direct  current  power  circuit  receives  current  from 
the  power  company’s  direct  current  bus-bars,  and  the  load  produced 
by  it  is  recorded  by  a Bristol  recording  watt-meter. 

The  maximum  amount  of  power  demanded  by  the  department  at  any 
instant  is  indicated  by  the  sum  of  the  quantities  shown  at  that  instant 
on  the  charts  of  the  three  above  mentioned  instruments. 

Each  single  phase  feeder  circuit  and  the  600  volt  direct  current 
circuit  is  provided  with  an  integrating  watt-hour  meter. 

The  street  lighting  circuits  are  equipped  with  two  such  meters. 

The  two  phase  “Tide  Flats”  circuit  has  an  integrating  watt-hour 
meter  connected  in  one  of  its  phases,  the  practice  being  to  multiply 
the  amount  registered  by  a constant  of  two,  the  result  being  accepted 
as  the  total  amount  of  power  consumed  on  both  phases  of  the  circuit. 
This  practice  will  be  mentioned  later  under  its  proper  heading. 

Two  Bristol  recording  volt  meters  are  connected  to  the  two 
phases  of  the  department’s  bus-bars.  The  purpose  of  these  instru- 
ments being  to  determine  any  variation  in  voltage  above  or  below 
2,500  volts,  the  amount  of  such  variation  being  speodfied  in  the  city’s 
contract  with  the  power  company,  and  limited  to  three  per  cent. 

Each  alternating  current  feeder  circuit  (with  the  exception  of  the 
two  phase  “Tide  Flats”  circuit)  is  equipped  with  a regulator,  which 
permits  of  separate  voltage  regulation  of  each  circuit  so  supplied. 

There  are  also  installed  thirteen  constant  current  transformers 
and  a series  street  lighting  regulator  in  connection  with  the  fourteen 
street  lighting  circuits. 

During  the  investigation  the  following  meters  were  carefully  tested: 

All  intergrating  watt-hour  meters,  the  graphic  recording  watt-meter, 
the  direct  current  Bristol  recording  watt-meter. 

All  potential  and  series  transformers  connected  with  above  meters. 

In  the  making  of  tests  the  following  instruments  were  used: 
Westinghouse  portable,  single  phase  watt-meter,  style  No.  34418. 
serial  No.  104. 

Thomson  A.  C.  Am.  meter,  style  No.  76999.

These  instruments  were  examined  at  the  testing  laboratory  of 
the  University  of  Washington  immediately  prior  to  use  in  this  investi- 
gation. Copies  of  standardization  certificates  are  included  in  the 
supplement  to  this  report  and  the  originals  thereof  are  filed  in  the 
office  of  the  Commissioner  of  Public  Works. 

Watt-hour  meters  on  panels  1,  2,  3,  4 and  11  are  connected  with 
their  series,  or  field,  coils  in  circuit  between  the  bus-bars  and  the 
feeder  regulator,  while  their  shunt,  or  potential,  coils  are  connected 
across  the  circuit  beyond,  or  on  the  line  side  of  the  regulator.  This 
manner  of  connecting  is  plainly  incorrect,  and  introduces  an  error 
in  the  amount  registered,  which  is  proportional  to  the  voltage  varia- 
tion, caused  by  the  regulator,  above  or  below  the  voltage  of  the  bus- 
bars. It  is  impossible  to  arrive  at  the  exact  amount  of  the  error 
in  the  present  case,  but  it  is  reasonable  to  assume  an  average  voltage 
on  these  feeders  not  less  than  5 per  cent,  above  that  of  the  bus-bars. 
It  may  be  assumed  that  from  this  cause  alone  the  bills  rendered  by 
the  Seattle-Tacoma  Power  Company,  for  power  consumed  on  the 
circuits  affected,  are  not  less  than  5 per  cent,  in  excess  of  a proper 
charge  for  same. 

The  following  table  is  compiled  from  meter  tests  made  during  this 
investigation.  The  “kilowatt  hours  registered”  column  and  the  two 
error  entries  marked  * are  derived  from  information  received  from 
tire  Chief  Clerk’s  office. 

The  meter  error  at  3/5  load  has  been  used  whenever  a reading 
at  that  load  was  available;  when  no  reading  at  3/5  load  could 
be  made,  the  percentage  of  error  at  that  point  has  been  derived  by 
a process  of  interpolation.  All  meters  exhibiting  an  error  of  less 
than  2 per  cent,  at  3/5  load  are  assumed  to  be  commercially  correct.

Attention  is  called  to  copies  of  meter  tests,  which  are  included 
in  the  supplement  to  this  report,  the  originals  thereof  having  been 
filed  in  the  office  of  the  Commissioner  of  Public  Works. 

Each  test  was  made  in  the  presence  of  an  authorized  representa- 
tive of  the  power  company,  who  has  attached  his  signature  to  the 
original  test  above  mentioned. 

The  defective  and  improperly  connected  meters  should  be  cor- 
rected at  once,  and  all  meters  should  be  inspected  at  least  once  each 
six  months. 

As  above  mentioned,  the  two  phase  “Tide  Flats”  circuit  is  provided 
with  a watt-hour  meter  in  one  of  its  phases  only.  This  was  done 
apparently  upon  the  theory  that  the  load  carried  by  this  circuit  was 
evenly  balanced  between  its  two  phases,  a condition  rarely  met  with  in 
practice.  It  is  recommended  that  the  other  phase  of  the  circuit  be 
provided  with  a watt-hour  meter  at  once. 

The  graphic  recording  watt-meter,  which  is  installed  on  the  power 
company’s  main  feeders  for  the  purpose  of  ascertaining  the  load  upon 
the  city’s  bus-bars,  was  tested  between  6:35  p.  m.  and  7 p.  m., 
February  25th.  The  result  of  three  observations  made  at  this  time, 
with  a load  varying  from  4,000  to  4,500  horsepower,  shows  this  instru- 
ment to  be  approximately  2 per  cent,  high  under  the  heavier  loads. 
A record  of  this  test  is  included  in  the  supplement  hereof. 

The  Bristol  recording  watt-meter,  which  indicates  the  load  upon 
the  600  volt  direct  current  power  circuit,  was  tested  at  11  a.  m., 
February  25th.  The  load  upon  this  circuit  is  of  an  extremely  variable 
nature.  The  result  of  the  tests  made,  however  (as  shown  in  the  sup- 
plement), is  evidence  of  the  commercial  correctness  of  this  instrument. 

All  feeder  regulators  and  constant  current  street  lighting  trans- 
formers are  placed  in  the  basement  directly  beneath  that  part  of  the 
building  occupied  by  the  department’s  switchboard. 

The  extremely  crowded  arrangement  of  this  apparatus  creates  a 
condition  of  great  hazard,  not  only  as  the  possible  cause  of  a serious 
interruption  to  the  service,  but  as  a menace  to  the  lives  of  all  those 
attendant  upon  it. 

All  of  the  older  station  wiring  is  of  poor  design  and  workmanship 
and  is  very  much  crowded. 

Owing  to  the  lack  of  available  space  in  the  power  company’s 
building  (the  design  of  which  is  little  adapted  to  the  department’s 
requirements),  it  is  impossible  to,  in  any  considerable  degree,  remedy 
these  conditions,  and  steps  should  be  immediately  taken  toward  the 
removal  of  the  department’s  apparatus  to  more  commodious  quarters. 

This  subject  will  be  mentioned  later  under  another  heading.

METER  DEPARTMENT 

This  department,  which  should  occupy  a position  of  the  greatest 
importance,  is  practically  destitute  of  every  facility  requisite  to  the 
proper  performance  of  its  functions.  Such  instruments  as  are  pro- 
vided are  old  and  out  of  adjustment.  The1  number  of  men  employed 
is  sufficient  only  to  the  execution  of  the  most  imperative  demands, 
while  less  pressing  but  equally  important  work  is  left  without  atten- 
tion. No  criticism  of  the  men  employed  is  here  intended,  as  the 
conditions  under  which  they  labor  are  such  that  better  results  could 
be  attained  by  no  others. 

The  meter  department  has  its  quarters  in  a small  room  partitioned 
off  from  the  Chief  Clerk’s  office  in  the  City  Hall.  This  room  it 
shares  with  the  Nernst  lamp  trimmers,  who  occupy  fully  one-half  of 
the  available  space.  Here  one,  or  at  times,  two  men  are  employed 
in  the  repairs  and  adjustment  of  watt-hour  meters. 

Meter  readers  are  employed  in  a sufficient  number,  but  very 
properly  they  are  fully  occupied  in  reading  meters  and  are  available 
for  no  other  work  of  importance. 

New  meters  are  installed,  as  required,  on  customer’s  premises, 
after  which  little  attention  is  paid  to  them  unless  the  customer  com- 
plains, or  the  possibility  of  error  is  brought  forcibly  to  the  attention 
of  the  department  in  some  other  way. 

A thorough  meter  test  is  impossible,  owing  to  the  lack  of  proper 
facilities,  and  upon  account  of  inaccuracies  in  the  instruments  now 
used  as  standards  by  the  department.  During  the  progress  of  the 
present  investigation  thirty-seven  (37)  watt-hour  meters  were  exam- 
ined on  customers’  premises.  One  test  only  of  each  meter  was  made, 
and  that  under  as  nearly  a full  load  as  could  be  secured.  All  meters 
within  2 per  cent,  of  accuracy  were  considered  as  being  commercially 
correct.  The  results  are  as  follows: 

13  correct. 

12  fast. 

12  slow. 

Copies  of  the  test  sheets  made  are  filed  with  the  Commissioner  of 
Public  Works. 

Owing  to  the  shortness  of  the  period  of  time  available  for  this 
work,  no  attempt  was  made  to  ascertain  the  condition  of  these  meters 
except  where  operating  under  the  loads  given.  Lyman  C.  Reed,  in  his 
“American  Meter  Practice,”  has  very  ably  discussed  the  subject  of 
losses  in  meters  and  the  result  of  his  analysis  shows  that,  under 
conditions  generally  met  with,  it  is  reasonable  to  expect  “a  general 
loss  of  15  per  cent,  of  the  current  delivered  apd  that,  too,  by  meters 
which,  on  loads  of  20  per  cent,  of  their  capacity,  are  commercially 
correct.” 

While  this  statement  was  made  in  1903,  since  which  date  there 
has  been  some  considerable  improvement  in  the  design  and  manufac- 
ture of  integrating  watt  meters,  it  is  reasonable  to  assume  that  under 
conditions  prevailing  in  the  City  Lighting  Department,  fully  15  per 
cent,  of  all  power  delivered  to  customers  fails  to  be  registered  upon 
the  dials  of  the  department’s  meters. 

The  tests  made,  so  far  as  they  were  extended,  showed  an  approxi- 
mately equal  division  of  correct,  fast  and  slow  meters  at  full  load. 


12 


CITY  OF  TACOMA  LIGHTING  DEPARTMENT. 


The  same  meters  tested  at  fractional  loads,  under  which  they  usually 
operate,  would  have  shown  themselves . to  be,  in  majority,  decidedly 
slow. 

From  the  foregoing  it  is  evident  that  in  no  branch  of  the  depart- 
ment is  it  more  important  that  proper  facilities  be  provided  than  in 
the  meter  department. 

Each  meter  should  be  inspected,  and  thoroughly  tested,  upon  the 
customer’s  premises  at  least  once  each  twelve  months.  For  this  pur- 
pose not  less  than  four  properly  equipped  inspectors  should  be 
appointed.  The  duties  of  these  men  should  extend,  not  only  to  the 
meters  in  their  districts,  but  to  the  character  of  the  load  carried 
upon  them.  There  is  prevalent,  amongst  certain  customers  of  elec- 
tricity in  the  city  of  Tacoma,  a sincere  belief  that  the  amounts 
charged  them  for  the  service  furnished  are  excessive;  notwithstanding 
the  fact  that  the  rate  per  kilowatt  hour  is  extremely  low  as  compared 
with  that  established  in  other  cities  of  the  world. 

There  is  a good  and  sufficient  reason  for  this  belief  in  the  fact 
that  probably  nowhere  else  is  there  in  use  a larger  number  of  low 
grade  and  inefficient  incandescent  lamps. 

Out  of  363  lamps  which  were  in  daily  use,  and  which  were  observed 
and  tested  for  “watts  consumed  per  rated  candlepower”  in  the  con- 
sumers’ houses  scattered  over  every  district  of  the  city,  only  eight 
(8)  lamps  were  found  which  were  rated  by  their  manufacturers  as 
“A”  grade;  all  of  the  remainder  of  these  lamps  were  either  “B” 
grade,  or  refilled,  and  their  power  consumption  per  rated  candle- 
power  varied  from  4.8  to  5.5  watts.  A power  consumption  of  3.5 
watts  per  candlepower  is  considered  fair. 

The  majority  of  the  observed  lamps  were  intended  for  operation 
upon  110  volt  circuits,  while  actually  the  voltage  of  the  circuits  upon 
which  they  were  used  varied  from  107  to  125  volts.  In  very  few 
instances  was  a voltage  of  110  observed  in  the  residence  section  of 
the  city  during  the  early  hours  of  the  evening. 

The  result  of  this  injudicious  placing  of  lamps  upon  circuits  to 
the  voltage  of  which  they  are  not  adapted,  and  also  the  result  of  poor 
voltage  regulation,  has  been  to  blacken  and  seriously  shorten  the 
useful  life  of  practically  all  incandescent  lamps  used  in  the  residence 
districts  of  the  city. 

The  useful  life  of  a 3.5  watt  lamp  is  approximately  600  hours  of 
burning  at  normal  voltage.  At  the  end  of  this  period  the  lamp  will 
have  deteriorated  to  very  nearly  80  per  cent,  of  its  initial  candle- 
power,  and  its  consumption  of  power  per  candlepower  will  have 
increased  from  3.5  to  4.3  watts,  or  22.8  per  cent. 

The  following  table  gives  the  effect  of  voltage  variations  upon 
this  “useful  life”  period  of  a 3.5  watt  lamp,  and  also  shows  its  power 
consumption  in  watts  per  candlepower  at  the  beginning.  This  quan- 
tity is  increased  by  about  23  per  cent,  at  the  end  of  the  useful  life 
period,  when  the  candlepower  of  the  lamp  has  been  reduced  to  80  per 
cent,  of  its  initial  output.  At  this  point  it  is  most  economical  to 
destroy  the  lamp  and  replace  it  with  a new  one,  as  a further  use  of 
the  old  lamp  results  in  a rapid  decrease  in  candlepower  and  an 
increase  in  electricity  consumed  per  candlepower,  reaching  in  some 
cases  a value  as  high  as  17  watts  per  candlehour.

A study  of  the  above  table  makes  evident  the  importance  of  good 
regulation.  This  subject  will  be  discussed  further  under  its  own  head- 
ing. 

The  statement  has  been  made  previously  in  this  report,  in  reference 
to  the  lamps  which  are  actually  in  use  upon  the  City’s  circuits,  that 
“their  power  consumption  per  rated  condle-power  varied  from  4.8  to  5.5 
watts.”  It  must  be  borne  in  mind  that  these  quantities  are  not  to  be 
considered  as  the  power  consumed  per  actual  candle-power,  which,  in 
some  instances,  must  have  nearly  approached  15  watts,  owing  to  the 
worn  out  condition  of  the  lamps. 

These  inferior  lamps,  requiring  an  excessive  current,  worn  and 
blackened  by  high  voltage  and  age,  constitute  a reason  for  complaint 
upon  the  part  of  the  customers,  which  is  sufficient  to  account  for  any 
general  dissatisfaction  which  may  have  been  felt  during  the  past  win- 
ter. Conditions  were  peculiarly  aggravated  by  heavy  additions  to  the 
load  upon  all  circuits  during  the  summer  and  autumn  of  1907,  without  a 
corresponding  increase  in  capacity  of  line  and  transformers. 

To  overcome  line  losses  occasioned  by  these  conditions,  the  de- 
partment increased  the  voltage  upon  certain  circuits,  both  at  the  sub- 
station and  by  the  installation  of  “booster”  transformers  upon  the 
lines.  No  attempt  could  be  made  to  replace  lamps  already  in  use  by 
those  of  higher  voltage,  as  the  department  has  no  control  over  larrups, 
and  the  raising  of  line  voltage  resulted  in  the  blackening  of  all  lamps 
upon  the  circuits  affected. 

In  a few  instances  complaints  may  have  been  due  to  a misunder- 
standing occasioned  by  a change  in  dates  of  meter  readings  which 
made  necessary  the  rendering  of  bills  in  certain  districts  covering 
periods  in  excess  of  thirty  days.  Such  misunderstandings  are,  how- 
ever, easily  rectified. 

The  principal  and  only  real  cause,  due  to  poor  lamps  and  over- 
loaded circuits  and  transformers,  is  just  and  should  be  remedied. 

This  subject  has  been  discussed  under  the  present  heading,  as  the 
remedy,  so  far  as  the  lamps  themselves  are  concerned,  would  be  pro- 
vided by  a recognized  meter  department. 

It  is  recommended  that  legislation  be  enacted  authorizing  the 
furnishing,  by  the  department,  of  all  8,  16  and  32  c.  p.  incandescent 
lamps  of  plain  design,  used  upon  its  circuits,  and  raising  the  rates 
charged  for  current  by  the  addition  of  one  cent  per  kilowatt  hour  to 
the  present  rates. 


14 


CITY  OF  TACOMA  LIGHTING  DEPARTMENT. 


Based  upon  the  renewal  of  each  16  c.  p.  incandescent  lamp  at  the 
expiration  of  600  hours  of  burning,  the  cost  to  the  City  for  lamps 
alone  would  be  very  nearly  6 mils  per  kilowatt  hour.  An  additional 
4 mils  per  kilowatt  hour  should  almost  exactly  cover  all  other  expenses 
incident  to  the  free  renewal  of  lamps. 

Business  houses  using  arc  lamps  or  Nernst  lamps  instead  of  in- 
candescent lamps,  may  be  excepted  from  the  increased  rate. 

It  is  further  recommended  that  the  business  connected  with  the 
free  renewal  of  lamps  be  made  a part  of  the  duties  of  the  meter  de- 
partment, in  whose  hands  there  should  be  at  all  times  accurate  in- 
formation concerning  voltage,  etc.,  at  the  point  where  the  lamps  were 
to  be  used. 

Lamps  should  be  renewed  at  the  rate  of  a 16  c.  p.  lamp  (or  equiv- 
alent thereof)  for  each  35  K.  W.  H.  consumed,  this  being  very  nearly 
the  consumption  of  a 3.5  watt,  16  c.  p.  lamp,  during  a period  of  600 
hours. 

Samples  taken  from  each  barrel  of  incandescent  lamps  should  be 
carefully  tested  both  by  photometer  and  for  power  consumption.  Lamps 
returned  by  customers  in  apparently  good  condition  should  be  tested 
and,  if  found  to  be  so,  should  be  re-issued. 

The  working  force  of  the  meter  department  should  consist  of  a 
foreman,  possessing  a thorough  knowledge  of  the  details  of  meter  con- 
struction, adjustment  and  repair.  He  should  also  be  competent  to 
direct  and  carry  on  tests  of  transformers,  arc  lamps,  etc. 

Subordinate  to  the  foreman  there  should  be  the  four  inspectors 
mentioned  above,  one  thoroughly  competent  electrical  mechanic,  one 
lamp  tester,  and  all  of  the  meter  readers. 

The  meter  department  should  be  provided  with  the  following  set 
of  standard  testing  instruments: 

1 Watt  meter. 

1 Am.  meter. 

1 Volt  meter. 

Series  and  potential  transformers  for  above. 

1 Photometer. 

*The  above  instruments  should  be  of  the  best  make,  of  laboratory 
type  and  of  the  highest  standard  of  accuracy.  They  should  be  re- 
tained at  all  times  in  the  testing  room  and  should  constitute  standards 
in  the  calibration  of  the  department’s  other  instruments. 

At  least  once  each  six  months  these  laboratory  instruments  should 
be  compared  with  the  standards  kept  in  the  nearest  testing  laboratory. 
In  addition  to  the  above,  the  department  should  be  supplied  with  the 
following  portable  instruments: 

2 Watt  meters — indicating. 

2 Sets  series  transformers. 

1 Rotating  watt  pieter. 

2 Potential  transformers. 

2 Am.  meters — A.  C. 

1 Mili  volt  meter,  D.  C. 

1 Set  shunts  for  same. 

2 Volt  meters,  A.  C.  and  D.  C. 

1 Split  series  transformer. 

1 Am.  meter  calibrated  for  same. 


CITY  OF  TACOMA  LIGHTING  DEPARTMENT.

The  cost  of  all  necessary  instruments  should  not  exceed  fourteen 
hundred  dollars. 

The  installation  and  maintenance  of  all  arc  and  Nernst  lamps  can 
be  carried  on  more  efficiently,  and  with  better  results,  under  the 
direction  of  the  meter  department  foreman. 

It  is  therefore  recommended  that  all  arc  and  Nernst  lamp  repair- 
men, trimmers  and  all  those  engaged  in  the  installation  of  these  lamps, 
be  placed  within  the  jurisdiction  of  the  foreman. 


LINE  CONSTRUCTION  DEPARTMENT 

Under  this  heading  will  be  included  all  that  pertains  to  the  City’s 
pole  lines,  distributing  circuits  and  transformers.  There  is  entered 
in  the  supplement  hereof  a brief  description  of  each  commercial  pri- 
mary circuit  and  the  600-volt  direct  current  power  circuit.  The  same 
order  has  been  preserved  as  was  given  in  the  description  of  sub-station 
equipment. 

Immediately  following  the  description  of  the  circuits  are  lists  of 
all  transformers,  showing  the  capacity  and  connected  load  of  each. 
These  lists  are  also  grouped  in  the  order  of  circuits  given  above. 

The  greater  part  of  the  matter  included  under  this  heading  is  a 
compilation  of  the  department’s  records. 

To  verify  conclusions  arrived  at  relative  to  energy  losses,  tests 
were  made  as  hereinafter  described. 

No  attempt  was  made  to  ascertain  definitely  the  losses  in  the 
secondary  circuits,  as  the  magnitude  of  such  an  undertaking  within 
the  time  specified  for  this  investigation  precluded  the  possibility  of 
reaching  any  satisfactory  result.  However,  from  a general  considera- 
tion of  the  characteristics  of  all  secondary  circuits,  and  from  such 
observations  as  it  was  possible  to  make,  an  average  loss  of  3 per  cent, 
of  power  delivered  may  be  assumed. 

The  information  contained  in  the  transformer  lists  (in  the  supple- 
ment) is  evidence  of  a great  lack  of  transformer  capacity  in  practi- 
cally all  circuits,  some  transformers  having  connected  fully  500  per 
cent,  of  the  rated  load  capacity.  This  circumstance  is  a very  large  fac- 
tor in  the  causes  which  produce  bad  regulation;  and  it  also  results  in 
abnormal  maintenance  charges,  due  to  the  number  of  burned  out  trans- 
formers. 

While  it  is  an  easy  matter  to  secure  transformers  having  full  load 
efficiencies  ranging  from  90  per  cent,  to  98  per  cent.,  in  accordance 
with  their  capacities,  the  “all  day”  efficiency  of  transformers  in  actual 
service  is  an  entirely  different  matter. 

This  is  due  to  the  fact  that  transformer  losses  are  made  up  of 
two  general  components,  copper  loss  and  iron  loss;  the  former  is  pro- 
portional to  the  square  of  the  current  flowing  through  the  transformer, 
while  the  latter  is  independent  of  the  load  and  constitutes  a continuous 
leak. 

A transformer  having  a full  load  efficiency  of  98  per  cent,  may 
very  readily  have  an  “all  day”  efficiency  of  90  per  cent.;  in  the  smaller 


16 


CITY  OF  TACOMA  LIGHTING  DEPARTMENT. 


capacities  the  difference  is  even  greater.  For  the  purpose  of  esti- 
mating power  losses,  the  transformer  losses  will  be  assumed  to  be  10 
per  cent,  in  this  report. 

Observations  of  the  loads  carried  by  the  various  circuits  were 
made  at  the  sub-station.  In  some  cases  the  Westinghouse  single  phase 
portable  watt  meter  No.  104  was  used,  while  in  others  the  load  was 
computed  'from  the  disk  speeds  of  the  integrating  watt  meters  installed 
on  the  feeder  panels. 

Power  factors  were  computed  by  comparing  the  volt-amperes  in 
dicated  with  the  watts.  Line  losses  were  calculated  from  the  voltage 
drop  at  various  points  in  the  several  circuits,  as  shown  by  readings  tak- 
en, at  such  points,  with  Weston  volt  meters  4668  and  4775,  and  poten- 
tial transformers  262121  and  205318,  under  varying  loads  and  power 
factors. 

The  working  organization  of  the  Line  Construction  Department  is 
under  a foreman  and  consists  of  a varying  number  of  sub-foremen, 
linemen  and  helpers. 

Sizes  of  wire  are  in  all  cases  given  in  Brown  and  Sharpe  wire 
gauge. 

MASON  LIBRARY  CIRCUIT. 

This  primary  circuit  consists  of  No.  00  gauge  copper  wire  from  the 
sub-station  to  the  corner  of  Prospect  and  North  Twenty-first  streets, 
a distance  of  approximately  14,500  feet.  Beyond  this  point  the  cir- 
cuit extends  nearly  3'V2  miles,  the  size  of  conductors  gradually  re- 
ducing to  No.  4 gauge. 

The  total  connected  load  is  approximately  350  K.  W.  The  greatest 
actual  load  observed  was  150  K.  W.,  at  90  per  cent,  power  factor. 

Calculated  losses  in  primary  conductors  aggregate  5.7  per  cent, 
of  power  delivered  to  transformers.  A booster  transformer  is  installed 
at  North  33d  and  Proctor  streets,  by  the  means  of  which  the  voltage 
of  the  circuit  at  that  point  is  raised  about  10'  per  cent. 

While  the  percentage  of  losses  in  this  circuit,  beyond  Prospect  and 
North  Twenty-first  streets,  is  excessive,  the  amount  of  load  upon  that 
portion  of  the  circuit  is  relatively  small,  as  compared  with  the  terri- 
tory covered. 

It  is  possible  that  the  present  arrangement  fulfills  the  require- 
ments in  as  economical  a manner  as  possible. 

The  transformers  on  the  circuit,  while  in  some  cases  heavily  over- 
loaded, are,  in  general,  of  sufficient  capacity. 

The  feeder  panel  at  the  sub-station  should  be  equipped  with  a 
compensated  volt  meter,  to  permit  of  close  regulation  at  Prospect 
and  North  Twenty-first  streets. 

OLD  TOWN  CIRCUIT. 

The  primary  circuit  from  sub-station  to  Eighth  street  and  Tacoma 
avenue  is  of  No.  0 gauge  copper  wire;  from  this  point  to  the  vicinity 
of  Yakima  avenue  and  North  Eighth  street,  it  is  of  No.  00  gauge.  A 
second  branch,  all  of  No.  00  wire,  reaches  the  above  point  from  the 
sub-station  via  I street;  near  Yakima  avenue  and  North  Eighth  street 
the  two  branches  are  tied  together. 

Minor  branches  and  secondary  circuits  cover  territory  east  of 


CITY  OF  TACOMA  LIGHTING  DEPARTMENT.

Prospect  and  south  of  Division  streets,  and  extend  to  vicinity  of  Me- 
Carver  and  North  Thirtieth  streets. 

The  total  connected  load  is  approximately  705  K.  W.  The  greatest 
actual  observed  load  was  170  K.  W.  @ 90  per  cent,  power  factor. 
Losses  in  conductors  from  tests  made  are  2.5  per  cent,  of  power  de- 
livered to  transformers. 

Voltage  should  be  kept  constant  at  Yakima  avenue  and  North 
Eighth  street.  A compensated  volt  meter  should  be  installed  at  the 
sub-station  for  this  purpose.  The  transformers  in  this  cricuit  are 
heavily  overloaded  and  secondary  circuits  show  excessive  losses. 

The  branch  running  to  McCarver  and  North  Thirtieth  streets  is  of 
No.  1 gauge  wire.  The  drop  in  voltage  on  this  branch  at  8:20  p.  m., 
March  15tli,  was  160  volts  or  7 per  cent,  of  the  voltage  of  the  circuit 
at  the  point  mentioned. 

The  size  of  the  wire  in  this  branch  should  be  increased  to  double 
its  capacity  for  one-half  the  distance  from  Yakima  avenue  and  North 
Eighth  street  to  the  end  of  the  line. 

Secondary  circuits  should  be  inspected  and  increased  in  capacity 
where  necessary.  All  joints  should  be  soldered,  including  service 
connections. 

SOUTH  TACOMA  AND  SIXTH  ADDITION  CIRCUIT. 

This  primary  line  consists  of  two  branches,  both  of  No.  0 gauge 
wire,  extending  from  the  pole  near  the  sub-station  to  the  corner  of 
K and  Center  streets,  a distance  of  approximately  7,000  feet. 

At  the  latter  point  the  circuit  divides,  one  branch  extending  to 
South  Tacoma,  the  other  covering  the  district  lying  to  the  east  thereof. 
Tlie  total  connected  load  on  this  circuit  is  approximately  700  K.  W. 
The  greatest  observed  load  was  320  K,  W.  @ 92  per  cent,  power  factor. 
Booster  transformers  are  installed  at  Forty-seventh  and  Union  streets, 
and  Thirty-sixth  and  K streets;  at  both  points  the  voltage  is  raised 
nearly  10  per  cent. 

The  total  primary  loss  in  this  circuit,  including  booster  trans- 
formers, is  approximately  8 per  cent,  of  the  power  delivered  to  the 
transformers. 

The  circuit  should  be  divided  at  the  sub-station,  and  separate 
feeder  panels  should  be  arranged,  one  controlling  the  South  Tacoma 
branch,  the  other  the  Sixth  Addition  circuit. 

Under  the  present  arrangement  it  is  impossible  to  secure  even  fair 
regulation,  owing  to  the  great  difference  in  length  and  load  distribu- 
tion in  the  two  branches. 

Both  circuits  should  be  increased  in  carrying  capacity  to  that  of 
No.  00  gauge  from  the  sub-station  to  the  vicinity  of  K and  Center 
streets. 

Compensated  volt  meters  should  be  provided  upon  each  panel,  and 
adjusted  for  the  approximate  “load  centers”  of  each  circuit. 

Secondaries  should  be  inspected  for  unsoldered  joints,  and  should 
be  reinforced  where  necessary. 

Transformers  on  this  circuit,  as  a whole,  are  ample  in  capacity. 

LOWER  PACIFIC  AVENUE  CIRCUIT. 

This  circuit  consists  of  No.  00  gauge  wires  from  the  sub-station  to 
the  vicinity  of  Twenty-sixth  and  D streets;  from  this  point  to  Fifty- 


18 


CITY  OF  TACOMA  LIGHTING  DEPARTMENT. 


ninth  and  East  H streets,  the  line  consists  of  No.  4 gauge  con- 
ductors. 

The  total  connected  load  amounts  to  approximately  600  K.  W.,  the 
greater  portion  of  which  lies  between  the  sub-station  and  the  inter- 
section of  Twenty-sixth  and  D streets. 

The  greatest  observed  load  was  260  K.  W.  at  85  per  cent,  power 
factor.  In  terms  of  power  delivered  to  transformers,  the  loss  in  the 
primary  circuit  is  approximately  2.5  per  cent,  between  the  sub-station 
and  the  extremity  of  the  No.  00  copper;  beyond  this  point  the  losses 
are  excessive,  due1  to  lack  of  copper  capacity. 

However,  the  comparative  load  carried  upon  the  No.  4 gauge  ex- 
tension is  small  at  present,  having  been  relieved  recently  by  the 
removal  of  a 40  horsepower  motor,  which  had  previously  been  in- 
stalled at  its  southern  extremity  in  Bismarck. 

It  is  very  probable  that  the  necessity  will  arise  within  the  near 
future  of  increasing  the  size  of  wire  used  for  a considerable  distance 
beyond  the  present  terminus  of  the  No.  00  gauge  copper. 

The  circuit  should  be  watched  carefully  and  no  considerable  in- 
crease in  load  should  be  accepted  upon  the  portion  of  the  circuit  men- 
tioned, without  adequate  provision  being  made  in  capacity. 

This  circuit  forms,  with  the  south  section  of  the  C and  Jefferson 
streets  circuit,  a two-phase  power  feeder. 

It  is  recommended  that  all  transformers  (except  those  feeding  two 
phase  motors)  lying  south  and  west  of  the  intersection  of  Delin  street 
and  Pacific  avenue  be  cut  over  to  the  C and  Jefferson  street  circuit. 
This  will  result  in  establishing  a more  nearly  balanced  condition  of 
load  between  the  two  phases. 

A compensated  volt  meter  should  be  installed  upon  the  feeder  panel 
and  adjusted  for  the  new  center  of  load  established,  after  the  re- 
arrangement of  transformers  suggested  above. 

Especial  attention  is  called  to  the  overloaded  condition  of  trans- 
formers on  this  circuit,  which  should  be  relieved  at  the  earliest 
possible  moment. 

TACOMA  AVENUE  CIRCUIT. 

The  Tacoma  avenue  circuit  is  constructed  of  No.  00  copper  for  a 
distance  of  about  150  feet  from  the  sub-station;  from  this  point  the  line 
consists  of  No.  0 gauge  wire  (with  the  exception  of  four  spans  of 
No.  2)  to  its  end. 

The  total  load  connected  amounts  to  approximately  470  K.  W. 

The  greatest  actual  load  observed  was  190  K.  W.  @ 90  per  cent, 
power  factor.  Approximate  loss  in  primary  wires  is  2.9  per  cent,  of 
power  delivered  to  transformers.  The  size  of  wire  in  this  circuit 
should  be  No.  00  gauge  from  the  station  to  the  corner  of  Thirteenth 
and  D streets,  a distance  of  approximately  2,700  feet. 

All  service  furnished  east  of  alley  between  C and  D streets  from 
this  circuit  should  be  transferred  to  either  the  C and  Jefferson  streets 
or  Commerce  street  circuits. 

The  Tacoma  avenue  circuit  should  be  kept  free  of  two  phase  motors, 
and  switchboard  arrangements  should  be  made  to  permit  of  its  being 
fed  from  either  phase.  Transformers  are,  in  general,  overloaded,  and 
secondary  circuits  in  places  evidence  excessive  losses  due  to  lack 
of  sufficient  metal  and  poor  joints.  All  joints  should  be  soldered. 


CITY  OF  TACOMA  LIGHTING  DEPARTMENT.

The  feeder  panel  should  be  furnished  with  a compensated  volt 
meter  set  for  the  corner  of  Thirteenth  and  D streets. 

PACIFIC  AVENUE  CIRCUIT. 

This  circuit  is  constructed  of  No.  00  gauge  wire  throughout,  with 
the  exception  of  a short  extension  upon  its  northern  extremity  which 
is  of  No.  4. 

Its  total  connected  load  is  approximately  550  K.  W.  The  greatest 
load  observed  was  360  K.  W.  @ 88  per  cent,  power  factor.  The  ap- 
proximate loss  in  primaries  is  2.7  per  cent,  of  power  delivered  to 
transformers.  (This  amount  is  calculated,  no  tests  having  been 
made.) 

The  transformers  on  this  circuit  show  overloads,  but  are  now 
being  replaced  by  those  of  larger  capacity. 

As  a whole  the  regulation  is  good,  such  variations  as  do  occur 
being  caused  in  a great  part  by  the  overloaded  condition  of  the 
transformers. 

The  Pacific  avenue  circuit  should  be  relieved  of  a portion  of  its 
load  by  the  Commerce  street  circuit,  which  has  ample  line  capacity. 

A compensated  volt  meter  should  be  installed  at  the  sub-station 
and  adjusted  for  the  voltage  at  or  near  the  corner  of  Pacific  avenue 
and  Eleventh  street. 

This  circuit  should  be  entirely  free  from  two-phase  or  large  single 
phase  motors.  All  such  motors  now  connected  can  be  carried  upon 
the  Tide  Flats  power  circuit. 

SIXTH  AVENUE  CIRCUIT. 

This  circuit  is  divided  at  Nineteenth  and  Hood  streets  into  two 
general  branches. 

The  first  consists  of  No.  00  gauge  wire  from  the  sub-station  to  the 
corner  of  Ainsworth  and  Sixth  avenue,  at  which  point  a booster  trans- 
former is  installed,  raising  the  voltage  at  that  point  about  10  per  cent. 
The  distance  from  the  sub-station  to  the  booster  is  nearly  10,600 
feet.  From  this  point  the  feeder  runs  west  on  Sixth  avenue  to 
Adams  street,  and  is,  in  the  greater  part,  constructed  of  No.  4 gauge 
copper  wire.  Minor  branches,  running  north  and  south,  are  of  No.  6 
and  No.  8 gauge  wire.  Formerly  a back  feeder  extended  east  from 
Sixth  avenue  and  Sprague  street.  This  has  been  recently  removed 
and  the  above  mentioned  booster  installed.  Incandescent  lamps 
serviced  from  this  feeder  east  of  Sprague  street  are  very  much 
blackened,  which  is  the  probable  result  of  cutting  transformers  over 
from  the  back  feeder  to  the  main  circuit  before  lowering  the  voltage 
thereon. 

The  total  connected  load  on  this  branch  is  approximately  300 
K.  W.  and  the  greatest  observed  load  162  K.  W.  @ 90  per  cent,  power 
factor.  (This  latter  amount  is  estimated  from  readings  made  cover- 
ing the  entire  circuit.)  Approximate  primary  losses  are  12 ^ per 
cent,  of  power  delie vered  to  transformers. 

The  second  branch  of  the  Sixth  avenue  circuit  consists  of  No.  0 
gauge  wire  from  Nineteenth  and  Hood  streets  to  Eleventh  and  Tacoma 
avenue,  a distance  of  about  3,630  feet.  From  this  point  to  the  end 
of  the  line  at  Tacoma  avenue  and  North  Sixth  street,  it  is  built 


20 


CITY  OF  TACOMA  LIGHTING  DEPARTMENT. 


of  No.  4 gauge  wire.  A back  feeder  of  No.  6 gauge  wire  runs  on 
Tacoma  avenue  from  North  Sixth  to  North  First  street. 

The  total  connected  load  on  this  branch  aggregates  362  K.  W. 
approximately,  and  the  greatest  observed  load  was  186  K.  W.  @ 
90  per  cent,  power  factor.  The  primary  losses  in  this  branch  are 
nearly  8 per  cent,  of  the  power  delivered  to  the  transformers. 

This  circuit  should  be  divided  into  two  independent  circuits  at 
the  sub-station,  as  it  is  impossible  to  secure  satisfactory  regulations 
with  the  present  arrangement. 

A compensated  volt  meter  should  be  set  on  the  first  branch  for 
the  voltage  at  Sixth  avenue  and  Sprague  street,  and  another  on 
the  second  branch  for  Tacoma  avenue  and  Division  street. 

The  copper  in  both  branches  of  this  circuit  is  entirely  inadequate 
and  should  be  increased  by  the  addition  of  105,500  circular  mils  in 
the  first  branch  from  the  sub-station  for  a distance  of  7,500  feet. 

In  the  second  branch  the  No.  0 wire  should  be  extended  from 
its  present  terminus  at  Eleventh  and  Tacoma  avenue  for  a distance 
of  20,000  feet,  in  place  of  the  No.  4 wire  now  used. 

The  transformers  on  this  circuit  are  very  heavily  overloaded. 

The  secondary  circuits  should  be  carefully  inspected  and  increased 
in  capacity  where  necessary. 

C AND  JEFFERSON  STREETS  CIRCUIT. 

This  circuit  branches  north  and  south  from  the  pole  at  the  corner 
of  Nineteenth  and  Jefferson  streets. 

The  north  branch  consists  of  No.  00  gauge  wire,  which  is  gradu- 
ally reduced  to  No.  6 at  the  High  School  building.  The  south  branch 
consists  of  No.  00  gauge  wire  from  the  sub-station  to  the  vicinity  of 
Thirtieth  and  D streets,  from  which  point  to  the  end  of  the  line  it 
consists  of  No.  4 wire. 

The  north  branch  carries  a total  connected  load  of  nearly  325 
K.  W.,  while  135  K.  W.  approximately  is  connected  in  the  south 
branch.  The  greatest  actual  load  observed  was  172  K.  W.  at  86 
per  cent,  power  factor. 

Assuming  this  load  to  be  divided  in  proportion  to  the  connected 
load  between  the  two  branches,  results  in  121  K.  W.  in  the  north 
branch  and  51  K.  W.  in  the  south  branch,  all  at  86  per  cent,  power 
factor. 

Approximate  primary  losses  in  the  north  branch  are  equivalent  to 
3 per  cent,  of  the  load  delivered  to  the  transformers,  while  in  the 
south  branch  such  losses  constitute  but  0.83  per  cent,  of  power  so 
delivered. 

The  secondary  losses  in  both  branches  are  in  some  cases  excessive 
and  the  transformers  are  in  general  overloaded. 

As  the  south  branch  of  this  circuit  is  operated  in  connection  with 
the  lower  Pacific  avenue  circuit  to  form  a two  phase  feeder,  and 
as  the  north  branch  constitutes  primarily  a lighting  circuit  servicing 
important  business  houses,  it  is  recommended  that  two  distinct  cir- 
cuits be  formed,  one  including  the  north  branch  and  the  other  the 
south  branch.  The  south  circuit  should  relieve  the  lower  Pacific 
avenue  of  sufficient  load  to  effect  a balanced  condition  between  them. 


CITY  OF  TACOMA  LIGHTING  DEPARTMENT. 


21 


Remarks  made  relative  to  capacity  of  lower  Pacific  avenue  cir- 
cuit apply  to  the  South  C and  Jefferson  streets  circuit  equally  as  well. 

Compensator  should  be  set  for  the  same  location  as  that  upon  the 
lower  Pacific  avenue  circuit. 

A compensated  volt  meter  should  be  installed  showing  voltage 
at  corner  of  Eleventh  and  C streets. 

Transformers  and  secondary  circuits  are  overloaded,  in  many  in- 
stances, in  both  north  and  south  branches. 

HILL  CIRCUIT. 

This  circuit  consists  of  No.  00  and  No.  0 gauge  copper  wire  form- 
ing a mesh  surrounding  blocks  between  Nineteenth  and  Thirteenth 
streets,  Tacoma  avenue  and  D street,  from  which  branches  of  No.  4, 
No.  6 and  No.  8 wire  are  run. 

The  total  connected  load  amounts  to  915  K.  W. 

The  maximum  observed  load  was  310  K.  W.  at  92  per  cent,  power 
factor. 

The  approximate  primary  losses  are  4.1  per  cent,  of  all  power  de- 
livered to  transformers. 

Compensator  should  be  set  for  the  voltage  at  I and  Thirteenth 
streets. 

While  additional  copper  is  required,  conditions  can  be  very  much 
improved  by  the  installation  of  larger  transformers,  and  overhauling 
the  secondary  circuits. 


“COURT  A”  CIRCUIT. 

This  feeder  from  the  sub-station  to  the  vicinity  of  Eighth  street 
and  Court  A is  formed  of  No.  00  wire;  from  this  point  to  its  northern 
extremity  at  the  foot  of  Sixth  street,  it  consists  of  No.  6 wire. 

The  total  connected  load  is  675  K.  W. 

The  greatest  actual  load  observed  was  196  K.  W.  @ 90  per  cent, 
power  factor. 

Approximate  primary  loss  is  2.3  per  cent,  of  power  delivered  to 
transformers.  Two  phase  motors,  or  large  single  phase  motors,  now 
connected  in  this  circuit  should  be  transferred  to  the  Tide  Flats 
circuit. 

COMMERCE  STREET  CIRCUIT. 

This  circuit  is  of  No.  0000  wire  from  the  sub-station  to  Thirteenth 
and  Commerce  streets;  where  it  branches  and  continues  north  on  both 
sides  of  Commerce  street  it  is  of  No,  00  and  No.  0 gauge  for  the 
greater  part  Of  the  way  to  Ninth  street,  where  it  ends. 

The  total  connected  load  on  this  circuit  is  about  400  K.  W.  No 
observation  was  made  of  actual  load. 

The  primary  loss  is  negligible  so  far  as  the  purposes  of  this  in- 
vestigation are  concerned.  Secondary  losses  are  very  considerable 
and  transformers  show  overloads. 

This  circuit  is  of  ample  capacity  to  relieve  other  more  heavily 
loaded  circuits,  which  are  now  carrying  secondaries  in  the  territory 
which  properly  belongs  to  it. 


22 


CITY  OF  TACOMA  LIGHTING  DEPARTMENT. 


TIDE  FLATS  CIRCUIT. 

This  circuit  is  a four-wire,  two-phase,  power  feeder  and  consists  of 
No.  00  gauge  wires  from  the  sub-station  to  Dock  and  Eleventh  streets; 
from  this  point  it  is  of  No.  4 wire  to  the  end  of  the  line  on  the  east 
hank  of  the  channel. 

The  total  connected  load  is  155  K.  W.  No  observations  were  made 
for  actual  load,  but  the  probabilities  are  that  it  is  not  less  than  100 
K.  W.  at  75  per  cent,  power  factor. 

Total  primary  losses  are  nearly  1%  per  cent,  of  power  delivered 
to  transformers. 

This  circuit  should  be  extended  from  Eleventh  street  north  on 
Pacific  avenue,  and  should  carry  all  motor  load  possible. 

DIRECT  CURRENT  CIRCUIT. 

For  a description  of  this  circuit,  see  supplement. 


SERIES  STREET  LIGHTING  CIRCUITS.

The  total  load  carried  aggregates  about  300  K.  W. 

These  circuits  are  constructed  of  No.  6 and  No.  8 gauge  wire. 

No  wire  smaller  than  No.  6 should  be  used  in  any  part  of  the  dis- 
tributing system,  except,  possibly,  in  making  service  connections, 
owing  to  lack  of  tensile  strength  in  the  smaller  sizes. 

All  secondary  circuits  should  be  thoroughly  grounded  and  all 
feeder  panels  equipped  with  automatic  circuit  breakers. 

The  constant  current  transformers  governing  the  street  lighting 
circuits  are,  in  some  cases,  heavily  overloaded;  a condition  im- 
possible to  relieve  until  more  space  is  provided  in  the  sub-station. 

The  total  losses  in  all  the  street  light  regulating  apparatus  are 
very  nearly  3 per  cent,  of  the  total  load  carried. 

MAPS  AND  RECORDS. 

A great  deal  of  excellent  work  has  recently  been  accomplished 
by  the  department  in  securing  information  to  be  used  in  the  compila- 


CITY  OF  TACOMA  LIGHTING  DEPARTMENT. 


23 


tion  of  a system  of  maps  and  records.  This  work  has,  for  some 
reason,  been  permitted  to  lapse  and  the  information  secured  by 
previous  effort  is  not  in  such  shape  that  it  can  be  used  to  the  best 
advantage. 

All  records  of  transformers,  incandescent,  arc  and  Nernst  lamps; 
all  records  of  circuits,  including  maps,  etc.,  should  be  in  the  custody 
of  an  experienced  electrical  engineer,  who  should  have,  under  the 
authority  of  the  City  Electrician  (or  Superintendent)  complete  juris- 
diction over  all  extensions  and  additions  to  the  distributing  system 
and  the  load  thereon. 

Maps  should  be  completed  at  the  earliest  possible  moment,  show- 
ing all  circuits,  and  having  entered  thereon  complete  information  con- 
cerning same. 

These  maps  should  be  drawn  to  a scale  of  not  less  than  one  inch 
to  eacn  100  feet  of  distance. 

Blue  print  copies,  properly  bound  and  indexed,  should  be  fur- 
nished all  departments  of  the  city  government  who  are  in  any  way 
interested. 

All  changes  should  be  immediately  posted  on  the  original  maps 
and  corrections  made  at  reasonable  intervals  in  the  copies.

From  the  above  table  it  may  seen  that  of  803,065  kilowatt  hours 
of  electrical  power  purchased  from  the  Seattle-Tacoma  Power  Com- 
pany, during  the  month  of  February,  approximately  190,276  K.  W.  H. 
or  23.69%  was  lost  in  distribution. 

While  the  maximum  total  load  observed  during  this  investigation 
was  but  slightly  in  excess  of  4,500  horse-power,  there  is  no  doubt  but 
that  demands  in  excess  of  5,000  horse-power  have  been  made  upon  the 
department  during  the  past  winter. 

As  additional  load  is  constantly  accepted,  there  is  no  doubt  but  that 
a demand  largely  in  excess  of  5,000  horse-power  will  be  placed  upon 
the  system  as  soon  as  the  days  shorten  sufficiently  to  produce  a coinci- 
dent store  and  residence  lighting  and  motor  load  peak.  Unless  satis- 
factory arrangements  can  be  made  during  the  present  summer  for  an 
additional  supply  of  power,  it  is  extremely  probable  that  the  depart- 
ment will  be  confronted  with  serious  difficulties  during  the  coming 
winter. 

It  is  recommended  that  efforts  be  made  to  secure  not  less  than 


CITY  OF  TACOMA  LIGHTING  DEPARTMENT. 


25 


1,000  horse-power  in  excess  of  the  quantity  at  present  reserved  by  the 
Seattle-Tacoma  Power  Company. 

It  is  further  recommended  that  there  be  appointed  a Board  of  Com- 
missioners, which  shall  consist  of  the  City  Engineer  and  two  other 
engineers  experienced  in  the  erection  of  hydro-electric  and  steam  elec- 
tric plants. 

This  Board  should  be  instructed  to  carefully  examine  such  water- 
power properties  as  may  lie  within  a reasonable  distance  of  the  City 
of  Tacoma.  If  any  be  found,  capable  of  development  to  the  extent  of 
not  less  than  ten  thousand  (10,000)  horse-power,  with  a load  factor  of 
30%,  which  can  be  acquired  by  the  City  and  developed  at  a reasonable 
price,  this  Board  should  be  instructed  to  prepare  plans  and  to  make 
estimate  of  the  cost  of  such  acquisition  and  development. 

If  no  such  waterpower  is  available,  then  should  it  be  required  that 
the  Board  of  Commissioners  prepare  complete  working  plans  and 
specifications  covering  the  erection  of  a steam  driven  electric  generat- 
ing station  of  not  less  than  three  thousand  (3,000)  horse-power,  and 
capable  of  being  increased  to  ten  thousand  horse-power  capacity. 

Immediate  action  should  be  taken  upon  the  recommendation  of  this 
Board,  and  a decision  reached  relative  to  same  without  delay. 

Respectfully  submitted, 


Consulting  Electrical  Engineer.
